The present disclosure relates generally to flow sensors, and more particularly, to devices and methods for providing a pressure drop through a flow sensor at a given flow rate. In one illustrative embodiment, a sensor assembly includes a housing with a first flow port and a second flow port. The housing may define a fluid channel extending between the first flow port and the second flow port, with a sensor positioned in the housing and exposed to the fluid channel. The illustrative sensor may be configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A flow restrictor may be situated in and integrally molded with at least one of the first flow port and the second flow port. The flow restrictor may be configured to accurately provide a pressure drop through the flow sensor at a given flow rate.
